$HOE-POLISHING DEVICE.

Application filed July 7, 1927. Serial No. 204,029.

The object of my invention is to produce a foot operated shoe polishing device in which the operator, by moving a treadle with his foot, will cause a polishing element to pass rapidly back and forth across the shoe to polish the same.

A. further object is to provide a device of the above character which will be durable, compact, easy to operate, in expensive to make and composed of few parts.

My invention comprises generally, a treadle and a polishing element operated thereby, which polishing element may be made removable and which is preferably yieldingly mounted, spring means being provided for yieldingly holding the treadle and the polish-' ing element in their normal positions.

A. practical embodiment of my invention is represented in the accompanying drawings, in which Fig. 1 represents the shoe polishing device in top plan, the polishing element being shown in full lines in its normal position at one side of the treadleand in dotted lines at the limit of its transverse movement at the other side of the treadle and also in an intermediate position.

Fig. 2 represents a side view of the device with the parts in their normal positions.

Fig. 3 represents a similar view with the parts in the positions they assume when the treadle is depressed.

l 4; represents a rear end view of the device.

Fl 5 represents an enlarged detail section showing the spiral slot and pin connection between the tread is operated rock shaft which carries the polishing element and its turning block.

The base of the device is draioted by l,

.which base may be provided with threesuitable legs 2, 2, 2, serving to hold the base firmly on its support in an upwardly and forwardly inclined position. The treadle 3 may be pivoted at its front end to the front end of the base by providing the base with two uprising ears l, 4 and the treadle with a dependin g 11%,,- 5 through which ears and lug a pivot pin 6 is passed.

The rear end of the treadle is yieldingly sup 'iorted by and spaced above the rear end of the base, in the present instance by providing a linl; comprising upwardly and for- \vardly inclined arms 7, 7, pivoted at their lower ends to the base by the pivot pin 8. The upper ends of these arms carry a pair of inwardly projecting pins 9, 9, on which are mounted rollers 1 1O exterior to the arms 7, l. A shaft turning block 11 is mounted on the pins 9, 9 between the arms 7, 7. A longitudinally disposed treadle operated rock shaft '12 passes through the depending lug 5 of the treadle and the turning block 11, the rear end of which shaft provided with a spiral groove 13 within which the inner ends of the pins 9, 9 are located. This rock shaft 12 is provided with a collar 14 which engages the inner face of the depending lug 5 of the treadle.

Beyond the front end of the trcadle a resilient arm is adjustably fastened to the rock shaft 12, in thepresent instance by means of a set screw 15 passing through the hub 16 of the arm into engagement with the said shaft. The resilient arm is herein shown as a closely coiled spring 17, the outer end of which is provided with a head 18 having lat eral ears 19, 19 from which long pins 20, 20 project rearwardly. The polishing element is shown as a tubular pad 21 of any material suitable for polishing such, for instance, as wool, which pad is removably carried by the pins 20, 20 by inserting the pins into the bore of said tubular pad.

The treadle 3 and the polishing element are yieldingly held in their normal positions with the polishing element at one side of the treadle by spring means which, in the present instance, comprises a coil spring 22 surrounding the rock shaft 12 and located between a collar E23, fixed on said shaft and a tubular extension Ql of the shaft turning block 11. A, lug 25 depending from the treadle 8 engages the rear face of the shaft turning block 11 when the parts are in their normal position for limiting the movements of the treadle and polishing element. A yielding pad 26 is provided on the base 1 in position, to receive the impact of the turning block 11 when the treadle is depressed.

When it is desired to polish the shoe, the foot is placed upon the treadle and the treadle is depressed. The downward movement of the inclined arms 7 will cause the rollers 10 to travel along the underside of the treadle 3, carrying therewith the shaft turning block 1l.with the pins 9 naturally moving along within the spiral groove 13 and thereby reclaiing the shaft 12. Upon releasing the pressure upon the treadle the spring 22 returns the elements to their normal position, again rocking the shaft but in the reverse direction.

The device thus is operated to cause the polishing element to pass rapidly back and forth across the shoe in yielding contact therewith. This yielding contact is obtained by the resilient arm 17 which carries the polishing element.

From the above description it will be seen that I have provided a very simple shoe polishing device and one in which the polishingclementisnot only caused to yieldingly engage the shoe as it passes back and forth across the same, but is also capable of being removed and replaced at any time.

Furthermore, it will be seen that thedevice may be easily operated as the rear end of the treadle rests upon the anti-friction rollers 10. 10 carried by the link 7 7 It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts Without departing from the spirit and scope of my invention; hence, I do not wish to be limited to theparticular embodiment herein shown and described, but what I claim is 1. Ina shoe polishing device, a base, a shoe supporting treadle pivoted thereon, a shaft disposed longitudinally with respect to the treadle, a resilientarm fast on said shaft,

a polishing element carriedby said arm. and means operated by the movement of the treadle for rocking said shaft to move the polishing element laterally across the-shoe of the operator on the treadle;

2. Ina shoe polishing device, a base, a shoe supporting treadle pivoted thereon. a shaft disposed longitudinally with respect to the treadle, a closely coiled spring arm fast on said shaft, a polishing element carried by saidarm, and means operated by the movement of the treadle for rocking said shaft to move the polishing'element laterally across the shoe of the operator on the treadle;

3. In a shoe polishing device, a base, a shoe supporting treadle pivoted at its front end thereon, a shaft disposed longitudinally With respect to the treadle, a resilient arm fast on said shaft beyond the front end of the-treadle and having rearwardly projecting pins, a tubular polishing element removably carried by said pins, andmeans operated by the movement'ofthe treadle for rock ing said shaft to move the polishing element laterallyacros's the shoe of the operator on i the treadle.

4. In a shoepolishing device, a base, a shoe supporting treadle pivoted at its front end thereon, a shaft disposed longitudinally with respect to the treadle, a closely coiled spring arm fast on Said shaft beyond the front end of the-treadle and having rearwardly projecting pins, a tubular polishing element removably carried by said pins, and means operated by the movement of the treadle for rocking said shaft to move the polishing element laterally across the shoe of the operator on the treadle.

5.
